Hello, I am trying to open an CS5 indd file and it is stating that I need to upgrade my plug-ins in order to open the file. I have version 7.0.5 on my iMac and the file I am trying to open was created using a CS5 also, but I just not sure what version it was. The plug-ins listed that I need to upgrade is a long list. Can someone please help me on how to do this as this is my first time.
It is quite doubtful that it was created in CS5. That error points to a file that was created in a later version. If it's only one file, put it in a dropbox folder and share a link to it here. Someone will open it for you and save back via IDML.
There is no guarantee everything will translate properly. And, if it was created in CS5, it may be corrupt.
